currently the checkout process is forcing a customer to enter billing address twice. once in the cart and then again on the paypal site. i thought that smith cart would prepopulate these fields in paypal. how do i achieve this? is there a setting in paypal that i'm missing, or in smith cart? or is this even possible?

I'm using paypal payments standard only, no other gateway is setup and i left the show paypal button unchecked. it appears that paypal wants the customer to either sign in or sign up. i don't care if they sign up with paypal, but i would at least prefer that the address fields are prepopulated when they get to paypal. too much hassle and many will drop the order. what else should i look for? thanks
